Application filed January 28, 1907. SeriaLNo. 354,547.

gan, have invented a new and useful Autm matic Printer for Paper-Rolls, of which the following is a specification.

This invention relates to printing attachments for paper rolls and has for its object to provide a comparatively simple and inexensivc. device of this character capable of eing 1rli uickly attached to or removed from and by means of which an advertisement or. other matter may be rinted on the pa er as the latter is unwoun fromthe roll.

further object of the invention is to provide the printing roller with spaced longitudinal barshaving convex side walls and de fining intermediate ty e-receiving recesses or grooves, "said type eing removably suported in position on the printing roller by ictional engagement with the convex walls ofthe grooves. Afurther object is to provide means .for yieldably supporting the rinting roller in contact with the pa er ro and means for permitting a limite rocking movement of the printing roller thereby to accommodate inequalities in the paper roll.

A still further ob1ect of the invention is to generally im rove this class of devices so as 'to increase t eir utility} durability and effiienc With these and'other objects in view the invention consists in the'construction and novel combination and arrangement of parts hereinafter fully'described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claim.

In the accompanying drawings forming a part ofthis specification: Figure 1 is a transverse sectional view of a printing attachment constructed in accordance with my invention showing the same in position on a paper roll. Fig. 2 1s a perspective view of the printing attachment removed. 'Fig. 3 is a detail sectional vievt of one of the spaced disks.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawin s.

The improved device is princi ally desi nod for attachment to paper ro s and the li e for printing an advertisement? or other matter on the wrap ing aper as the latter is unwound from t e ro l, and by way of illustration is shown in connection with a paper roll of the ordinary construction in which 5 designates the roller-supporting frame and 6 the paper roll.

The attachment consists of a lon itudinal bar or supporting member 7 to whidh are secured spaced plates or brackets 8 having their free ends extended beyond the adjacent lon itudinal edge ,of the bar and bent latera y to form terminal eyes 9 for the reception of the roller supporting frame or yoke,

indicated as a whole at 10.

The yoke 10 is provided with an intermediate off-set portion 11 and depending arms 12 the free ends of which are provided with terminal enlar ements or bearings 13 in which is journa led the shaft 14 of the printing roller.

The printing roller consists of spaced disks or Wheels 15 having their inner edges cut away at the periphery of the wheel and provided with spaced recesses or sockets 16 for the race tion of the adjacent ends of the cylindrica connecting bars or-rods 17.

The bars 17 are spaced apart to form intermediate grooves or recesses for the reception of the removable type 18, the latter being preferably formed of rubber or other yieldable material and clamped in position by frictional engagement with the convex walls of the rods'17, as best shown in Fig. 2 of the drawing.

interposed between the disks or wheels 15 and resting'on the shoulders 19 formed by trela segmental recesses is a plate 19 prefera dis s and which forms a closure or bottom for the t pe-receiving grooves thereby to ret ent t e same from slipping through or hetweenthe longitudinal bars when the t pe are clamped in position on the printing ro ler.

Slidab y mounted on the arms 12 of the roller supporting yokeare sleeves or collars 20 having sockets or recesses 21 formed therein for the reception of the trunnions of the inking roller 22, the latter being yieldably supported in eng ement with the tinting rolier by means 0 coiled springs 23 interposed between the movable collars 20 and suitable fixed collars 24 carried by the arms 12 of the yoke.

The ieldable surface of the inking roller prefera 1y terminates short of the opposite ends thereof to form terminal flanges 25 curved to conform to the contour of the which bear against the periphery of the disks 01' wheels 15 and serve to assist in centering the inking roller and also prevent the ink on the roller from comingvin contact with the wheels or disks andcons equently smearing the paper when the device isbperatedf T e supporting member or bar 7 is secured to the ro tends through'the bar 7 and roll supportin frame and is secured in position by means j a nut or similar clamping device 27, there I being a Washer 28 interposed between the.

bar- 7 and the roll supportin frame so as to permit a-slight rocki'ngor t' ting movement f of the bar 7 'andfthus permit the printing roller to'conformto the ]paper roll should one end thereof be lower -t anmotion.

- Secured-to the upper surface of the bar 7 are one .or more'coiled springs 29 haying pa er'rol.

their intermediate portions extended to-form "arms :30. which bear against the lateral off set portionl 1 of the pivoted yoke or printing rollerfraine and serve to yieldablysupport the printing when in enga ement wit paper 'rolls'o that asthe ro er diminishes in size by reason of the'removal of a portion of the the 'paperthe printing roller" and its associated parts. 'wilhe inkin and printing rollers are, prefer ably inclose ina suitable casing or housing 31 soas to protect the inking 'rol fromdust and'otherforeign matter. e

erabl be removed and;the bars 17- detached when the latter become-broken'or otherwise in-,

lured'from constant use:

supporting frame by means of a bolt or similar fastening device 26 which exthe other which. would necessarily give it a slight wabbling 20.

follow the contour of said er and type,

.The 0 posite ends-of the shaft 14 are prefv threaded and extended .throu h the, whee sor disks forengagement' wit suitable clamping nuts 32whereb'y the disk may 5 Witnesses:

It will thus be seen-that when a longitudinal pull is exerted von the free end of the wrap ing paper'the inking roller by fric-- tiona en agement with sa1d paper will revolve wit n the casing or housin and travel over the surface of the inking ro ler so that a further movement of the paper will cause the typeto press against the paper and thus leavethe imprint of the ty e thereon;

From the. foregoing escription it is thought that the constructionand operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary. f i 1 Having thusdescribed the invention what is claimed is: p v Q I g The combination with a' paper roll frame, of a sup orting member mounted on the frame an providedwith spaced brackets, a poke pivotally mounted in the brackets and aving an intermediate lateral off-set per tion and its opposite ends provided with ter= minal bearings, a printing roller journaled in in the presence of two-witnesses.
